I've used the 30 cal 155, 6.5 139 and 123 with wonderful results
The 6mm 105 was the first I saw this behavior. As I said, the shoulder shot stuff died very quickly. It was the double lung rib shot stuff that surprised me with the 100 yard death runs. They left decent blood from the exit side to follow. I was just shocked because I've never seen one that caught a 105 amax or 108 eld go more than 30 yards.
